TL;DR: In this article, a source for correlated pairs of atoms characterized by two opposite momenta and two spatial modes forming a Bell state only involving external degrees of freedom was demonstrated, and the state of the emitted atom beams was characterized by observing strong number squeezing up to -10 dB in the correlated two-particle modes of emission.

TL;DR: In this paper, the authors discuss coherent atom optics and atom interferometry techniques for molecular beams in sect. 1 and for trapped atoms in Sect. 3, and then describe tools and experiments that allow us to probe the evolution of quantum states of many-body systems by atom interference.

TL;DR: In this article, it was shown that thermalization and the breakdown of integrability in the one-dimensional Lieb-Liniger model caused by local three-body elastic interactions is suppressed by pairwise quantum correlations when approaching the strongly correlated regime.

TL;DR: In this article, the Luttinger liquid model is used to study the non-equilibrium dynamics in a quenched pair of 1D Bose gases with density imbalance.

TL;DR: In this paper, the spectral properties of a magnetic guide were investigated for a wide range of field gradients and the spatial distribution of the spin polarization were analyzed, and the effects due to an additional homogeneous bias field constituting a Ioffe-Pritchard trap were explored equally.
